With a series of alternative materials and rapid development, especially in the application of high performance glass beads to reduce thermal conductivity and reduce deep-sea oil and gas recovery feasible.With the deep undersea oil pipeline requires the development of deeper and more to geographic location requirements increase. When depth and stressful environment, usually filled with glass beads apply foam insulation, which makes deep-sea pipeline to extend long 50km or farther underwater.
Currently the use of hollow glass microspheres filled polymer synthesis deep strong buoyancy material has been applied in foreign countries.According to reports, the current foreign developed high compressive strength, low density buoyancy material is an epoxy binder, filled with hollow glass beads and a large number of additives, such as lightweight composite buoyant material used in deep-sea submarine, in the deep seaIt can withstand high pressure, and in the basic conditions for a long time does not absorb moisture.Although China has been carried out in this field for many years of research, but in terms of diving with buoyant material properties are still lagging behind the international advanced level.
